China OEM Waterproof Steel Tape Measure Custom Measuring Tape

The deformation of the tape is too large to fail. Why didn't it fail; The winding in the tape measure is very long, with a wide range from complete relaxation to complete contraction. The entire travel of the tape measure includes a margin at both ends, so the tape measure will not fail. There is no difference in pulling force between pulling one meter long and pulling two meters long; The winding of the tape measure is very thin, and the amount of deformation during tightening is also very small, so the reaction force is very small, and the change in force is not felt when pulling the tape measure.

Tape measure is a commonly used measuring tool in daily life. What you often see is a steel tape measure, which is commonly used in construction and decoration, and is also one of the necessary tools for families. It is divided into fiber tape measures, tape measures, waist circumference measures, etc. Lu Bangzhi, Feng Shui zhi, and Wen Gong zhi are also steel tape measures. The reason why the tape can be rolled up is that there is a spring inside the tape. When pulling out the measured length, it actually lengthens the scale and the length of the spring. Once the measurement is completed, the spring inside the tape will automatically shrink, and the scale will also shrink under the action of the spring force, so the tape will be rolled up.
